  • the webs are fixed in a suitable manner and then a heat treatment, in particular a Subjected to vulcanization and curing process.
  • the object underlying the invention is achieved by an apparatus for coating cylindrical or conical bodies, in particular of rolls, in which at least one calender for Production and smoothing of a body coating web from a tempered coating composition is provided, wherein the calender, especially in close proximity, a rotatable, to be coated Body is assigned.
  • a rotatable, to be coated Body is assigned.
  • the coating composition is a Polymer, in particular an elastomer, or other plastic materials.
  • the calender width at least the width of the coated Part of the body corresponds.
  • This can be a Body Coating be made at least approximately the Width of the part to be coated of the body to be coated equivalent.
  • the calender must be designed so that the production a Arthurbe Anlagengsbahn in a width is possible, the width corresponds to the part to be coated. By this measure It is not necessary to wind single strips, but it can a web over the entire width of the section to be coated be applied. As a result, production seams are avoided, whose Swelling could leave traces in the finished coating. If in this application of a part to be coated the Speech is, of course, the case should be included, that the body should be coated over the entire width. In In this case, the section corresponds to the entire body width. if the entire body surface should be coated, so must the Calender width at least the width of the entire, to be coated Correspond to the body.
  • the body to be coated means for pressing the Body coating web assigned to the body to be coated are.
  • a pressure roller which is the Body coating web presses against the body to be coated.
  • the invention is advantageously provided that between calender and body to be coated means for Trimming the elaboratebe Anlagensbahnbreite, in particular on the Width or approximately to the width of the part to be coated Body, are provided.
  • This embodiment is particularly of Advantage, if the calender and thus the calender rolls wider are formed as the part to be coated. Will the Body coating web approximately to the width of the coated Section is trimmed, so the advantage of being incomplete with advantage interconnected thoroughlybe AnlagenllsbahnstMail avoided. Furthermore, there are no production seams, especially as find spiral traces in the finished coating.
  • the Body coating web width for example, to one-half or one One third of the width of the part to be coated. At the However, it is most advantageous in any case, if the width of the Body coating web the width of the entire to be coated Part corresponds.
  • a particularly effective method of pruning the Body coating web width is given by the fact that as a means to Trimming the body coating web width at least one, but especially two spaced, with a cutting roller cooperating, rotating blades are provided. The distance of Both rotary knives then suitably match the width of the coating body.
  • Avoiding body coating is advantageous between calenders and to be coated body, especially in the transport direction behind the means for trimming the body coating web width provided continuous coating web storage.
  • this continuous coating web storage is made at least two spaced storage rollers, wherein at least one the storage roll is movable relative to the other storage roll, around the body coating web at a constant tension hold.
  • the storage roll is movable relative to the other storage roll, around the body coating web at a constant tension hold.
  • To maintain a constant tension of the body coating web ensure is at least one of the two rolls against the advantage Movably supported by a spring.
  • it can also be one Voltage measuring sensor be provided, via an electronic control system controls the position of the rollers to each other.
  • rolling ensures that it does not Air pockets in the coating or corrugations of the Body coating web comes on the body to be coated.
  • the calender rolls are formed heatable. This allows the Calendering process optimized and on the different Coating materials are adjusted.
  • the advantage is the risk incompletely connected Body coating strip avoided because the suppleness and Ready-to-use tack of the coating composition by the heating additionally improved.
  • additional heating be provided in particular before the calender.
  • the object underlying the invention is also by a Process for coating cylindrical or conical bodies, in particular of rolls, wherein first a coating mass rolled and smoothed to the required thickness by means of a calender, and then the resulting body coating web to one coating, in particular rotating, body, fed directly and this is then coated continuously.
  • Immediate feed of course implies that in the process guide rollers, Conveyor belts or latches, etc. are integrated.
  • With continuous coating is meant that the Body coating web in one or more layers on the zu Coating body is wrapped.
  • the proposed method thus ensures that the Roll immediately after calendering the body coating web this is coated.
  • a calender By the measure that for calendering the Body Coating a calender is used whose width at least the width of the part of the body to be coated Corresponds, ensures that a body coating web can be made, which is about the width of the coated Section, or the body to be coated corresponds. hereby In particular, seams and other defects in the finished Coating avoided. Also, the risk of being incomplete Minimized interconnected material layers.
  • the width of the Wegbe Mrsungsbahn is exactly to the required dimension adjusted by the body coating web before the actual coating process is curtailed, especially in about the width of the part of the body to be coated. Should the entire body will be coated, so will the Body coating track cut to about the width of the body.
  • the coating composition on a Temperature is controlled above room temperature. hereby can also dry at room temperature, non-sticky Mixtures process, since by the increase in temperature of the Coating mass also their stickiness is increased. By the bigger one Suppleness and confection of the warm Coating mass becomes the broke by trapped air and significantly reduces the formation of location separations.
  • the temperature of the Coating compound with advantage approximately between 40 ° C and 100 ° C.
  • the cutting remains the calender or a Coating mass reservoir be fed again.
  • This Recycling of the coating composition, in particular of the rubber mixture is in contrast to all known methods, in particular for Hand-made possible, because additional process steps in the separate calendering occur in the inventive method eliminated.
  • the tempered coating material 1, in particular a Polymer composition, in this application, a rubber compound is by two calender rolls of a calender 4 to a thickness between about 0.5 and 2 mm brought and smoothed.
  • the width of the calender is 4 and thus the calender rolls 2 and 3 are sized larger than the width the part of the body 5 to be coated, here a roller.
  • both calender rolls are heatable in this embodiment educated.
  • the width 6 of the Kirkbe Anlagenllsbahn 7 by two rotating, spaced knives 8, which against a Cutting roller 9 run, set.
  • the width 6 of the body coating web is approximately equal to the width of the body to be coated 5, since the body over its entire Width should be coated.
  • the excess part of Coating compound 10 will be back 11 between the Calender rolls 2, 3 transported.
